As a star, the Sun is heated to high temperatures by the conversion of nuclear binding energy due to the fusion of hydrogen in its core. This energy is ultimately transferred (released) into space mainly in the form of radiant (light) energy. In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale. Living organisms require available energy to stay alive, such as the energy humans get from food. Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The processes of Earth's climate and ecosystem are driven by the radiant energy Earth receives from the sun and the geothermal energy contained within the earth. Selected article Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (ex situ processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or in situ processing) by applying heat and extracting the oil via oil wells. The earliest description of the process dates to the 10th century. The industry shrank in the mid-20th century following the discovery of large reserves of conventional oil, but high petroleum prices at the beginning of the 21st century have led to renewed interest. As of 2010, major long-standing extraction industries are operating in Estonia, Brazil, and China. Its economic viability varies with the ratio of local energy input costs to energy output value. National energy security issues have also played a role in its development. Critics of shale oil extraction pose questions about environmental management issues, such as waste disposal, extensive water use and waste water management, and air pollution. Read more...

Wikinews on energy Renewable energy news Quotations "In recent years, new nations have entered enthusiastically into industrial production, thereby increasing their energy needs. This has led to an unprecedented race for available resources. Meanwhile, some parts of the planet remain backward and development is effectively blocked, partly because of the rise in energy prices. What will happen to those peoples?" – Pope Benedict XVI, 2007 "In order to prevent the harmful consequences that crude oil price volatility is having on the well-being of our people, it is urgent that we convene a World Leaders Summit to present alternative solutions to this serious problem, which could quite possibly be a significant shock to the prosperity of developing nations." – Leonel Fernández, 2005 Related portals Technology Nuclear technology Engineering Ecology Earth sciences Physics Transport Infrastructure Business & Economics Sustainable development Renewable energy Chemistry WikiProjects WikiProjects connected with energy: WikiProject Energy Oil megaprojects task force Other WikiProjects that may be of interest: WikiProject Environment WikiProject Technology WikiProject Biography Help Puzzled by energy?
